Cluster Computing [chapter]

Mark Baker, John Brooke, Ken Hawick, Rajkumar Buyya
2001 Lecture Notes in Computer Science  
This ownership often brings problems when attempting to form a cluster of workstations.  ...  Generally a workstation will be "owned" by, for example, an individual, a groups, a department, or an organisation. They are dedicated to the exclusive use by the "owners".  ...  The processing elements are interconnected by two parallel Ethernet networks with a peak capacity of 10 Mbps per network.  ...

Simulation Framework for Modeling Large-Scale Distributed Systems [article]

Dobre Ciprian, Cristea Valentin, Iosif C. Legrand
2011 arXiv   pre-print
Simulation has become the evaluation method of choice for many areas of distributing computing research.  ...  However, most existing simulation packages have several limitations on the size and complexity of the system being modeled.  ...  Generally, at any given moment of time, the CPU unit of the workstation is able to handle only one process, so if the context switching between processes takes longer that would take for the network message  ...
